Racism is nowhere as prevalent as it once was say 50 years ago, not saying it doesn't exist now but in evidential fact.
I agree. Years ago there was both racism (individuals with prejudice) and systemic racism - actual laws on the statutes that mandated different treatment based on race. Each probably perpetuated the other to some extent.
That is no longer the case. There are undoubtedly racists in the world (of all colors, we should note) but systemic racism as it's usually claimed doesn't appear to be a thing, even when justice departments have done lengthy investigations to find it.
Again, the trick you'll see is people pointing to individual act of racism and claiming it as evidence of systemic racism, or comparing things to the general population which is statistically incorrect and invalid.
The reason you know they do it intentionally to misrepresent things is that the stats are clear and easy to check. The stats show more black people commit crimes and the prison population largely reflects the population of those committing crimes.
To compare the general population would mean including more in the complete pipeline of "the system", because prison / justice is just the end part of it.
So why then don't they include the school system, when it comes to deciding if things are "systemically racist"? There seems to be way more evidence that schools are systemically racist if you compare "what goes in / what comes out" against the general population.
What could it possibly be? Surely not that teachers unions donate massive amounts to the democratic party? (98% of their political donations in 2020)
